Incorect derivation of a packet length in WebRTC in Google Chrome prior to 68.0.3440.75 allowed a remote attacker to potentially exploit heap corruption via a crafted video file.

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4165-1 advisory.

    Multiple security issues were discovered in Firefox. If a user were tricked in to opening a specially     crafted website, an attacker could potentially exploit these to cause a denial of service, bypass security     restrictions, bypass same-origin restrictions, conduct cross-site scripting (XSS) attacks, bypass content     security policy (CSP) protections, or execute arbitrary code.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of Firefox installed on the remote Windows host is prior to 70.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-34 advisory, including the following:

  - Incorrect derivation of a packet length in WebRTC in Google Chrome prior to 68.0.3440.75 allowed a remote     attacker to potentially exploit heap corruption via a crafted video file. (CVE-2018-6156)

  - In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to     document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber)     then resulted in a heap-based buffer over-read. (CVE-2019-15903)

  - When storing a value in IndexedDB, the value's prototype chain is followed and it was possible to retain a     reference to a locale, delete it, and subsequently reference it. This resulted in a use-after-free and a     potentially exploitable crash. (CVE-2019-11757)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The version of Firefox installed on the remote macOS or Mac OS X host is prior to 70.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-34 advisory, including the following:

  - Incorrect derivation of a packet length in WebRTC in Google Chrome prior to 68.0.3440.75 allowed a remote     attacker to potentially exploit heap corruption via a crafted video file. (CVE-2018-6156)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

This update for Chromium to version 68.0.3440.75 fixes multiple issues.
